Dental fusion should be included in differential diagnosis when panoramic radiograph reveals changes in tooth shape or size. The use of specialized dental photographic techniques can augment the dentists' knowledge and awareness of such conditions.
Dental fusion of impacted teeth may show up as a change in tooth shape and size on the first radiographic examination. This report presents an impacted maxillary third molar fused with a peg-like distomolar in a 20-year-old male. The patient presented with symptoms of localized periodontitis distal to the second molar, and radiographic examination revealed abnormal dental structure of the third molar. Surgical extraction of the impacted molar was the treatment of choice. The final diagnosis of fusion was based on data from ex vivo CBCT, photographs of the extracted tooth, and extracted tooth's sections using polarizing filters. Two-dimensional radiographs may conceal special dental anatomies. Visualization of such cases using CBCT and dental photography serves to educate dentists and reduce postoperative complications. Knowledge and awareness of possible dental abnormalities are of utmost importance for successful treatment planning.
当全景X线片显示牙齿形状或大小改变时，牙融合应纳入鉴别诊断。使用专业的牙科摄影技术可增强牙医对此类情况的认识。
阻生牙的牙融合在首次影像学检查时可能表现为牙齿形状和大小的改变。本报告介绍了一名20岁男性，其上颌第三磨牙与一颗钉状远中磨牙融合。患者表现为第二磨牙远中局部牙周炎症状，影像学检查显示第三磨牙牙齿结构异常。手术拔除阻生磨牙是首选治疗方法。融合的最终诊断基于体外CBCT数据、拔除牙齿的照片以及使用偏光滤镜的拔牙切片。二维X线片可能会掩盖特殊的牙齿解剖结构。使用CBCT和牙科摄影对这类病例进行可视化有助于培训牙医并减少术后并发症。了解并认识可能存在的牙齿异常对于成功的治疗计划至关重要。
